Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery. Background Art

[0002] Soybean is one of China's important food crops. my country is the world's largest soybean consumer, with an annual soybean consumption of more than 100 million tons and a gap of more than 90 million tons between supply and demand. In the past, before the soybean ridges were closed, the soybean ridge spacing was too large and the seedling spacing was too small. During a long period of the growth period (especially in the early stage of soybean growth), a large part of the light was not irradiated on the leaves, but on the ground between the ridges, and the light energy utilization efficiency was low. After the ridges were closed, due to the dense seedling spacing, the soybean leaves competed for light (the phototropism of the plant), and the soybean plants were very likely to grow upward, which led to lodging and reduced yields. Therefore, finding a scientific and effective planting method is of positive significance to the improvement of soybean yields in Northeast China. Summary of the invention

In order to cooperate with their mechanism for transferring fertilizer or transferring seeds, the present invention sets a corresponding mechanism (described in detail below). The large fertilizer box 1210 is a simple box body, and its mechanism for transferring fertilizer, transmission, etc. has been modified to cooperate with the present invention, as described below.

[0010] The front frame 13 (including the angle beam 1302 and the main beam 1304) is connected to the bracket mechanism 7 through a four-bar mechanism (the force-adding mechanism is installed on it). The four-bar mechanism is composed of a bracket mechanism connecting plate 707 and a cross beam 708. The front frame 13 is equipped with a fertilizer applicator mechanism 1, a ground wheel mechanism 2, a power wheel mechanism 10 and a power input mechanism. The bracket mechanism 7 is equipped with a large fertilizer box mechanism 12, a sowing unit mechanism 5, a grass-dividing wheel mechanism 3, a pressing wheel mechanism 6 and a hydraulic adjustment mechanism.

[0011] Front frame 13: Fertilizer mechanism mounting frames 1303 are installed on both sides of the angle beam 1302, and two fertilizer mechanisms 1 are respectively installed on the fertilizer mechanism mounting frames 1303 on both sides of the angle beam 1302; a support frame 1301 is installed on the side of the front end of the angle beam 1302.

[0012] A left gearbox 1313 and a right gearbox 1308 are respectively installed at both ends of the main beam 1304, and a hexagonal gearbox drive shaft 1307 is installed on the input drive shaft 131301 of the left gearbox 1313 and the right gearbox 1308; a single mounting frame 1305 is installed on the rear side of the main beam 1304, and a lateral position adjustment slot 1316 is opened on the single mounting frame 1305; the left gearbox 1313 and the right gearbox 1308 have the same structure, and both adopt Fig.39The no-tillage planter plant spacing adjustment gearbox, the hexagonal gearbox transmission shaft 1307 is a hexagonal shaft with a hexagonal end face, the hexagonal gearbox transmission shaft 1307 connects the left gearbox 1313 and the right gearbox 1308, and is used to synchronously transmit power to the left gearbox 1313 and the right gearbox 1308, respectively. Figure 4 and Figure 5 .

[0013] See Figure 6 and Figure 7 The output transmission shaft 131302 of the left gearbox 1313 is fixedly mounted with a hexagonal terminal transmission shaft input end gear 1309, which is connected to the hexagonal terminal transmission shaft output end gear 1312 through a chain, and the hexagonal terminal transmission shaft output end gear 1312 is mounted on the hexagonal terminal transmission shaft 1306, and the hexagonal terminal transmission shaft bracket 1310 connected by shafts at both ends of the hexagonal terminal transmission shaft 1306 is mounted on the main beam 1304. A chain tensioning auxiliary wheel 1311 is installed on the hexagonal terminal transmission shaft bracket 1310 between the output end gear 1312 of the driving shaft and the output end gear 1312 of the hexagonal terminal transmission shaft; after the hexagonal gearbox transmission shaft 1307 inputs power into the left gearbox 1313, it is transmitted to the output transmission shaft 131302 and the input end gear 1309 of the hexagonal terminal transmission shaft, and then transmitted to the output end gear 1312 of the hexagonal terminal transmission shaft through the chain, thereby driving the hexagonal terminal transmission shaft 1306 to rotate. The hexagonal terminal transmission shaft 1306 and the hexagonal terminal transmission shaft bracket 1310 can be connected by a bearing to ensure that the hexagonal terminal transmission shaft 1306 can rotate relative to the hexagonal terminal transmission shaft bracket 1310, and the tensioning auxiliary wheel 1311 is used to assist in adjusting the chain tightness between the input end gear 1309 of the hexagonal terminal transmission shaft and the output end gear 1312 of the hexagonal terminal transmission shaft.

[0014] See Figure 8 A fertilizer box power input gear 1314 is fixedly installed on the output drive shaft 131302 of the right gearbox 1308, and the fertilizer box power input gear 1314 is connected to the fertilizer box power output gear 1206 through a chain, and a chain tensioning auxiliary wheel 1207 is arranged between the fertilizer box power input gear 1314 and the fertilizer box power output gear 1206, and the wheel frame of the chain tensioning auxiliary wheel 1207 is installed on the fertilizer box base 1204; after the hexagonal gearbox drive shaft 1307 inputs power into the right gearbox 1308, it is transmitted to the output drive shaft 131302 and the fertilizer box power input gear 1314, and finally transmitted to the fertilizer box power output gear 1206 connected to it by chain, the chain tensioning auxiliary wheel 1207 has the same function as the tensioning auxiliary wheel 1311, which is used to assist in adjusting the chain tightness between the fertilizer box power input gear 1314 and the fertilizer box power output gear 1206.

[0015] Hydraulic adjustment mechanism: see Fig.10 and Fig.11 The tail end shaft of the cylinder body of the hydraulic cylinder 1320 is connected to the angle beam 1302, the front end shaft of the piston rod of the hydraulic cylinder 1320 is connected to the top of the hydraulic mechanism bracket 1315, the tail end of the hydraulic mechanism bracket 1315 is fixed on the big beam 1316, the two ends of the big beam 1316 are connected to the big beam seat 1318, the big beam seat 1318 is fixed on the main beam 1304, the ground wheel bracket 1317 is installed on the big beam 1316, and the ground wheel 1319 is installed on the ground wheel bracket 1317; the hydraulic cylinder 1320 and the hydraulic mechanism bracket 1315 are a triangle shape when viewed from the side, and the top of the piston rod of the hydraulic cylinder 1320 and the cylinder The tail ends of the body are connected in the form of an axis, that is, both ends of the hydraulic cylinder 1320 can rotate relative to their respective connecting parts, so that when the hydraulic cylinder 1320 is extended and retracted (that is, when the triangle changes), the two ends will not be locked. The hydraulic cylinder 1320 is a device that pulls the large beam 1316 to rotate. Through this mechanism, the angle between the angle beam 1302 and the ground wheel mechanism 2 (ground wheel bracket 1317 and ground wheel 1319) can be adjusted to ensure that the ground wheel 1319 is in contact with the power input wheel 1008, and the power is transmitted to the power input wheel 1008 through the rotation of the ground wheel 1319, so that it rotates synchronously. The large beam 1316 and the large beam seat 1318 are connected in the form of an axis, that is, when the large beam 1316 rotates, the large beam seat 1318 will not rotate. In this way, when the large beam 1316 rotates, the large beam seat 1318 and the main beam 1304 fixedly connected thereto will not move with it. The hydraulic cylinder 1320 plays a buffering role here, that is, when the angle between the angle beam 1302 and the ground wheel mechanism 2 changes, it will not change rigidly, but will change slowly according to the hydraulic pressure of the hydraulic cylinder 1320, thereby protecting the equipment.

[0016] Big fat box organization 12: Fig.12 The power transmission part of fertilizer transfer can be seen in the figure. Fig.13 The power transmission and the installation relationship between the entire large fat box mechanism and the frame (main beam 1304) can be seen from the side. Fig.13In the figure, due to the installation position relationship of the large fertilizer box mechanism 12, the installation base (fertilizer box base 1204) of the large fertilizer box mechanism 12 conflicts with the position of the hexagonal gearbox drive shaft 1307. Therefore, a bearing is used to connect the hexagonal gearbox drive shaft 1307 and the fertilizer box base 1204 in this part, so as not to affect the rotation of the hexagonal gearbox drive shaft 1307. The fertilizer box 1211 is installed on the upper end of the fertilizer box base 1204, and the fertilizer box base 1204 is installed on the main beam 1304. The fertilizer box power output gear 1206 is installed on the fertilizer box power fertilizer transmission shaft 1205. Both ends of the fertilizer box power fertilizer transmission shaft 1205 are installed on the fertilizer box base 1204 through bearings. The fertilizer box power fertilizer transmission shaft 1205 passes through the fertilizer transmission bin 1201, and fertilizer transmission blades are installed on the fertilizer box power fertilizer transmission shaft 1205. A fertilizer amount adjustment button 1202 is mounted on the fertilizer box power fertilizer transmission shaft 1205, and the fertilizer amount adjustment button 1202 extends from the side of the fertilizer transmission bin 1201. The fertilizer pipe 1203 at the lower end of the fertilizer transmission bin 1201, the fertilizer pipe 1203 The lower end is plugged into the upper end of the fertilizer outlet channel 105; the large fertilizer box 1211 is a box for holding fertilizers. Many conventional agricultural machinery also have large fertilizer boxes. At the bottom of the large fertilizer box, there is a mechanism that can adjust the amount of fertilizer by adjusting the knob. However, since the present invention has designed a new power transmission, in order to cooperate with the power transmission mechanism of the present invention, a power transmission rod with a hexagonal cross section (fertilizer box power fertilizer transmission shaft 1205) is designed. The power of the power transmission rod is achieved by connecting the power output gear 1206 of the fertilizer box with the power input gear 1314 of the fertilizer box through a chain. That is to say, the hexagonal gearbox transmission shaft 1307 transmits power to the right gearbox 1308 (from Figure 5 From the middle direction, it is a gearbox installed on the main beam 1304). The gearbox 1308 on the right side then transmits the power to the fertilizer box power output gear 1206 through its output transmission shaft 131302 and the fertilizer box power input gear 1314 on the output transmission shaft 131302 through a chain. The fertilizer box power output gear 1206 then drives the fertilizer blades in the fertilizer bin 1201 to rotate, thereby completing the fertilizer shifting (the function of setting the fertilizer blades is the same as that of the existing fertilizer blades. Since the fertilizer is a solid wet material, it is basically unable to rely on its own decline. In this way, it is necessary to set a fertilizer shifting function to shift and squeeze the fertilizer). The fertilizer amount adjustment button 1202 also has the same function as the existing fertilizer amount adjustment mechanism. The chain tensioning auxiliary wheel 1207 is an auxiliary function. Due to the particularity of the chain connection relationship, it is necessary to set a functional auxiliary wheel for chain tensioning. This auxiliary wheel of the present invention also plays the same role.

[0017] The force adding mechanism fixing frame 1102 is installed on the bracket mechanism connecting plate 707, and the bracket mechanism connecting plate 707 is installed on the single body mounting frame 1305 through the lateral position adjustment groove 1316. The elastic frames 1101 on both sides of the power mechanism are respectively placed on the cross beams 708 on both sides of the four-bar linkage. This mechanism is already a prior art (patent number: CN201620958971.1), and is used in conjunction with the four-bar linkage to install the front frame and the rear frame. The present invention also plays the same role. The force adding mechanism and the four-bar linkage are used in conjunction to connect the front frame 13 and the bracket mechanism 7.

[0018] The front end of the four-link (here refers to the front end of the beam 708) is axially connected to the bracket mechanism connecting plate 707, and the rear end of the four-link (here refers to the rear end of the beam 708) is axially connected to the front end of the bracket mechanism bracket 701; the front end of the force-adding mechanism is installed on the bracket mechanism connecting plate 707, and the elastic frames 1101 on both sides of the rear end are pressed on the bracket mechanism connecting plate 707, and the bracket mechanism connecting plate 707 is installed on the single-body mounting frame 1305 on the rear side of the main beam 1304 by bolts. The transverse adjustment groove opened on the single-body mounting frame 1305 is used to adjust the transverse position of the rear single body (referring to the bracket mechanism 7 connected by the four-link). Since general equipment will install multiple single bodies at the same time (the figure of the present invention shows three sets of single bodies), in order to avoid position installation problems, this transverse adjustment groove is set.

[0019] Power wheel mechanism 10: The power wheel mechanism mounting seat 1010 is mounted on the main beam 1304 of the mounting seat, one end of the power wheel mechanism bracket 1003 is mounted on both sides of the power wheel mechanism mounting seat 1010 through the power wheel mechanism shaft 1012, the front end of the power wheel mechanism bracket 1003, the power wheel mechanism mounting seat 1010 and the power wheel mechanism shaft 1012 have a large diameter through hole 1011, the hexagonal gearbox transmission shaft 1307 passes through the large diameter through hole 1011 and a power output gear 1001 is installed on one side, the large diameter through hole 1011 is sleeved outside the hexagonal gearbox transmission shaft 1307 but does not contact it, and the power output gear 1001 is connected to the power wheel mechanism through a chain. The power input gear 1006 is connected, and the power input gear 1006 is installed on the power input shaft 1009. Both ends of the power input shaft 1009 are installed on the power wheel mechanism bracket 1003 through bearings. A power input wheel 1008 is installed on the power input shaft 1009. The power input wheel 1008 is on the ground wheel 1319 on one side. A left auxiliary gear 1005 and a right auxiliary gear 1007 are respectively installed on both sides of the power input gear 1006 on the power wheel mechanism bracket 1003; the upper end of the power wheel mechanism assist spring 1004 is installed on the power wheel mechanism bracket 1003, and the other end is installed on the main beam 1304.

[0020] The power mechanism 10 is the main source of power for the large fertilizer box mechanism, the oral fertilizer mechanism, the seed box mechanism, etc. of the present invention. Fig.15 and Fig.16 ,from Figure 2 and Figure 3 It can be seen that the power mechanism corresponds to the ground wheel mechanism 2, and the input of power relies on the power input wheel 1008 contacting the ground wheel 1319 of the ground wheel mechanism 2, and the rotation of the ground wheel 1319 drives the power input wheel 1008 to rotate, and the power input wheel 1008 rotates with its wheel axle (power input shaft 1009), so that the power input gear 1006 installed on the side of the wheel axle will also rotate, and the power input gear 1006 will rotate with the power output gear 1001 through the chain, and since the power output gear 1001 is fixedly installed on the hexagonal gearbox drive shaft 1307, the rotation is transmitted to the hexagonal gearbox drive shaft 1307.

[0021] There are mounting ears 1002 on both sides of the power wheel mechanism mounting seat 1010. The power wheel mechanism mounting seat 1010 is fixed on the main beam 1304 through the mounting ears 1002 by bolts. The power wheel mechanism bracket 1003 and the power wheel mechanism mounting seat 1010 are connected through the power wheel mechanism shaft 1012. Therefore, the power wheel mechanism bracket 1003 and the power wheel mechanism mounting seat 1010 will not move with the movement. In other words, the power wheel mechanism mounting seat 1010 can move with the movement of the main beam 1304, but the power wheel mechanism bracket 1003 will not move with it.

[0022] Due to the position relationship, the hexagonal gearbox transmission shaft 1307 must pass through the end of the power mechanism 10 close to the main beam 1304, so the power wheel mechanism bracket 1003, the power wheel mechanism shaft 1012 and the power wheel mechanism mounting seat 1010 open a clearance hole (large diameter through hole 1011), and the hexagonal gearbox transmission shaft 1307 passes through this hole, but cannot contact the hole wall.

[0023] The working relationship between the power mechanism 10 and the ground wheel mechanism 2: the adjustment angle beam 1302 and the main beam 1304 are fixedly integrated, the tail end of the cylinder body of the hydraulic cylinder 1320 is installed on the adjustment angle beam 1302 in the form of an axis, the piston rod of the hydraulic cylinder 1320 is installed on one end of the hydraulic mechanism bracket 1315 in the form of an axis, and the other end of the hydraulic mechanism bracket 1315 is fixedly installed on the large beam 1316. The hydraulic mechanism bracket 1315, the hydraulic cylinder 1320, and the adjustment angle beam 1302 are installed in a triangular shape, the ground wheel mechanism 2 and the large beam 1316 are fixedly connected, and the main beam 1304 and the large beam 1316 are connected in the form of an axis (that is, when the large beam 1316 rotates, the main beam 1304 will not rotate), so that the power mechanism 10 installed on the main beam 1304 will not rotate. When the ground wheel 1319 of the ground wheel mechanism 2 contacts the ground, it will be slowly lifted up due to the pressure from above, and at the same time, it will drive the large shoulder 1316 and the hydraulic mechanism bracket 1315 to rotate clockwise. At this time, the power mechanism 10 is in a relatively static state relative to the ground wheel mechanism 2 until the ground wheel 1319 contacts the power input wheel 1008. In this way, during the movement, the power input wheel 1008 will also rotate through the rotation of the ground wheel, thereby transmitting power to the hexagonal gearbox drive shaft 1307.

[0024] It is explained here that since the power wheel mechanism bracket 1003 and the power wheel mechanism mounting seat 1010 are connected in the form of an axis, the power wheel mechanism bracket 1003 and the mechanism thereon are suspended by their own gravity (when there is no bottom support or any supporting contact, the bottom of the power wheel mechanism bracket 1003 is placed on the main beam 1304). When the ground wheel 1319 contacts the power input wheel 1008, it is very likely to lose contact. At this time, the elastic force of the power wheel mechanism assist spring 1004 will force the power input wheel 1008 to always keep in contact with the ground wheel 1319.

[0025] Transmission structure of seed box and fertilizer box: see Figure 23-Figure 27 The transmission mechanism includes three parts: power input part, seed box sowing transmission part, and fertilizer box fertilizer transmission part. The transmission mechanism is installed on the four-link structure and the bracket mechanism 7 in sequence, and its power source is the hexagonal terminal transmission shaft 1306 of the no-tillage planter spacing adjustment gearbox (left gearbox 1313) installed on the main beam 1304.

[0026] The bracket mechanism 7 is provided with a seed box and fertilizer box power input mechanism 706 installed on a side crossbeam 708 of the four-bar linkage mechanism, a seed box power input mechanism 704 is installed on the bracket mechanism bracket 701 under the corresponding seed box, a seed box chain tensioning mechanism 705 is installed on the bracket mechanism bracket 701 between the seed box power input mechanism 704 and the seed box and fertilizer box power input mechanism 706, a fertilizer box power input mechanism 702 is installed on the bracket mechanism bracket 701 under the corresponding fertilizer box, and a fertilizer box chain tensioning mechanism 710 is installed on the bracket mechanism bracket 701 between the fertilizer box power input mechanism 702 and the seed box and fertilizer box power input mechanism 706. The four-bar linkage is used to install a force-adding mechanism and is also used to connect the main beam 1304 and the bracket mechanism 7. The four-bar linkage is composed of a bracket mechanism connecting plate 707 and crossbeams 708 on both sides. Fig.23 and Fig.24 It can be seen that there are four cross beams 708 in total, forming a cubic shape. The cross beams 708 on the left and right sides are installed on the bracket mechanism connecting plate 707 and the bracket mechanism 7 in the form of an axis, so that the cross beam 708 can rotate around the axis. In addition, since the bracket mechanism connecting plate 707 is fixed on the main beam 1304, the bracket mechanism 7 has space to move up and down relative to the front frame 13.

[0027] Seed box and fertilizer box power input mechanism 706: A power transmission No. 1 gear 709 is installed on the hexagonal terminal transmission shaft 1306, and the hexagonal terminal transmission shaft 1306 is connected to a side beam 708 of the four-bar linkage through a bearing.

[0028] The structure of the seed box and fertilizer box is a relatively mature technology. Fig.17 and Fig.18 , the fertilizer box structure is shown in Fig.19 In order to facilitate the movement of seeds or fertilizers in the box, a moving mechanism is installed at the upper end of the sowing tube or the fertilizer moving tube at the bottom of the box (the sowing wheel 905 on the seed box and the fertilizer moving wheel 802 on the fertilizer box). In order to cooperate with these two moving mechanisms, the present invention is provided with a transmission mechanism (seed box and fertilizer box power input mechanism 706) on the bracket mechanism 7 for driving the two moving mechanisms to work normally. This transmission mechanism transmits the power of the hexagonal terminal transmission shaft 1306 to the seed box power input mechanism 704 and the fertilizer box power input mechanism 702 in sequence.

[0029] Seed box power input mechanism 704: see Fig.26The power transmission gear 709 is connected to the seed box mechanism large gear 70403 through a chain, and the seed box mechanism large gear 70403 is installed on the seed box mechanism shaft 70407. The seed box mechanism shaft 70407 passes through the bracket mechanism support 701 and is equipped with a bearing. The outer bearing bush is fixedly connected to the bearing sleeve 70408, and the bearing sleeve 70408 is fixedly installed on the bracket mechanism support 701. In other words, the inner bearing bush is connected to the seed box mechanism shaft 70407, and the outer bearing bush is fixedly connected to the bracket mechanism support 701 through the bearing sleeve 70408; the interior of the seed box mechanism shaft 70407 is hollow, and a seed box is inserted in the hollow. The inner shaft of the mechanism, one end of the inner shaft of the seed box mechanism is equipped with a manual adjustment button 70406, and the other end is a seed box contact head 70401, a seed wheel engagement groove 70410 is opened at the front end of the seed box contact head 70401, and an adjustment spring 70402 is set in the middle of the inner shaft of the seed box mechanism, one end of the adjustment spring 70402 is clamped on the hollow inner wall clamping platform of the seed box mechanism shaft 70407, and the other end is clamped on the rear end of the seed box contact head 70401; a longitudinal clamping groove 70409 is opened on the side of the seed box mechanism shaft 70407 close to the manual adjustment button 70406, and a locking pin 70405 is provided on the inner shaft of the seed box mechanism corresponding to the side of the longitudinal clamping groove 70409.

[0030] See the detailed structure and connection relationship of the seed box power input mechanism 704. Fig.26 , Fig.26 It is divided into two parts, the left side is the seed box power input mechanism 704, and the right side is the seed box chain tensioning mechanism 705. These two mechanisms are installed on the same side plate of the bracket mechanism support 701.

[0031] The seed box mechanism shaft 70407 is a hollow tube, which is installed on the bracket mechanism support 701 through a bearing. In order to facilitate the protection of the bearing, a bearing sleeve 70408 is added. The bearing sleeve 70408 is buckled on the bearing and fixedly connected to the bearing outer shell. The bearing sleeve 70408 is fixedly installed on the bracket mechanism support 701. In this way, the seed box mechanism shaft 70407 can rotate relative to the bearing sleeve 70408 and the bracket mechanism support 701. An inner shaft of the seed box mechanism is inserted into the hollow seed box mechanism shaft 70407, and a manual adjustment button 70406 is installed at one end of the inner shaft of the seed box mechanism, and the other end is an integrated seed box contact head 70401. The outer diameter of the seed box contact head 70401 is larger than the outer diameter of the inner shaft of the seed box mechanism. As can be seen from the figure, the manual adjustment button 70406 is on the outside of the bracket mechanism bracket 701, and the seed box contact head 70401 is on the inside of the bracket mechanism bracket 701. In this way, personnel can adjust the inner shaft of the seed box mechanism and the seed box contact head 70401 by plugging or rotating the manual adjustment button 70406 from the outside. A spring (adjustment spring 70402) is installed outside the inner shaft of the seed box mechanism and inside the seed box mechanism shaft 70407. In order to facilitate the installation of the spring, a clamping platform is set on the inner wall of the seed box mechanism shaft 70407, so that the two ends of the spring are respectively clamped between this clamping platform and the seed box contact head 70401. Fig.26 It is the length state of the engagement between the seed box contact head 70401 and the seeding wheel 905 of the seed box. When the seed box contact head 70401 needs to be disengaged from the engagement state with the seeding wheel 905, hold the manual adjustment button 70406 by hand and pull out the inner shaft of the seed box mechanism. At this time, not only the seed box contact head 70401 is disengaged from the seeding wheel 905 of the seed box, but also the locking pin 70405 is disengaged from the longitudinal groove 70409, and the adjustment spring 70402 is compressed. Then, the manual adjustment button 70406 is rotated at an angle of about 90 degrees until the locking pin 70405 is stuck on the outer edge of the seed box mechanism shaft 70407, thus completing the disengagement. Conversely, when the locking pin 70405 corresponds to the position of the longitudinal groove 70409, under the rebound action of the spring, the locking pin 70405 enters the interior of the longitudinal groove 70409 ( Fig.26 At the same time, the seed box contact head 70401 meshes with the seeding wheel 905 of the seed box. The seed wheel bite groove 70410 is a horizontal groove corresponding to the pin rod on the seeding wheel 905 of the seed box. When the seed box contact head 70401 meshes with the seeding wheel 905 of the seed box, the pin rod on the seeding wheel 905 of the seed box is stuck in the seed wheel bite groove 70410.

[0032] Two gears (the large gear 70403 of the seed box mechanism and the input gear 70404 of the fertilizer box) are installed on the seed box mechanism shaft 70407. Driven by the chain, these two gears will rotate at the same time. Therefore, when the seed box contact head 70401 is engaged with the seeding wheel 905 of the seed box, the power will be transmitted to the seeding wheel 905 to realize the movement of the seeds.

[0033] The seed box chain tensioning mechanism 705 is installed on the bracket mechanism support 701, placed between the seed box and fertilizer box power input mechanism 706 and the seed box power input mechanism 704 and connected to the chain, keeping the transmission belt or chain taut, thereby ensuring the efficient operation of the transmission system.

[0034] from Fig.26 Looking at the right side, the seed box chain tensioning mechanism 705 adopts a double-wheel tensioner (a basic tensioner 70504 and an auxiliary tensioner 70505). The two tensioners are connected to the tensioner bracket 70506 in parallel. In other words, the two tensioners can rotate independently relative to the tensioner bracket 70506, which makes it convenient for the chain to pass through in a rolling friction form. There is a fixed support shaft 70501 on the side of the tension wheel bracket 70506. The support shaft 70501 is inserted into the support sleeve 70502 in the form of an axis through the support shaft seat 70507. The support sleeve 70502 is fixed to the bracket mechanism bracket 701. The support shaft 70501 passes through the outer end of the tension wheel bracket 70506 and is limited by the support limit bolt 70508. A tension spring 70503 is installed on the bracket shaft seat 70507. The tail end of the tension spring 70503 is fixed on the bracket shaft seat 70507, and the other end is hooked on the outer edge of the tension wheel bracket 70506. Fig.26 As shown in the illustrated direction, the chain coming from the power input mechanism 706 of the seed box and fertilizer box (the gear power transmission gear No. 1 709 of this mechanism) passes from the bottom of the basic tensioner wheel 70504 to between the basic tensioner wheel 70504 and the auxiliary tensioner wheel 70505, and then passes from the upper part of the auxiliary tensioner wheel 70505 to connect with the large gear 70403 of the seed box mechanism, so that the chain between the gear power transmission gear No. 1 709 and the large gear 70403 of the seed box mechanism is tightened.

[0035] Fertilizer box power input mechanism 702: a fertilizer box input gear 70404 coaxial with the seed box mechanism large gear 70403 is installed on the seed box mechanism shaft 70407, the fertilizer box input gear 70404 is connected to the fertilizer box output gear 70202 through a chain, the fertilizer box output gear 70202 is installed on the fertilizer box mechanism shaft 70206, the fertilizer box mechanism shaft 70206 passes through the bracket mechanism support 701 and is equipped with a bearing, the bearing outer bush is fixedly connected to the fertilizer box shaft bearing sleeve 70204, and the fertilizer box shaft bearing sleeve 70204 is fixed on the bracket mechanism support 701; the fertilizer box mechanism shaft 70206 is hollow inside, and a fertilizer box manual adjustment rod 702 with a fertilizer box manual adjustment button 70201 at one end is provided. 09 is inserted in the hollow, the other end of the manual adjustment rod 70209 of the fertilizer box is the contact head 70207 of the fertilizer box, and a fertilizer wheel engagement groove 70208 is provided at the front end of the contact head 70207 of the fertilizer box, and an adjustment reset spring 70205 is mounted on the manual adjustment rod 70209 of the fertilizer box, one end of the adjustment reset spring 70205 is clamped on the hollow inner wall clamping table of the fertilizer box mechanism shaft 70206, and the other end is clamped on the rear end of the contact head 70207 of the fertilizer box; a fertilizer mechanism extension groove 70210 is provided on the side of the fertilizer box mechanism shaft 70206 close to the manual adjustment button 70201 of the fertilizer box, and a fertilizer box mechanism locking pin 70203 is provided on the manual adjustment rod 70209 of the fertilizer box corresponding to the side of the fertilizer mechanism extension groove 70210.

[0036] The fertilizer box power input mechanism 702 and the seed box power input mechanism 704 have roughly the same structure. Fig.25 The power is transmitted through the fertilizer box output gear 70202 and the fertilizer box input gear 70404 through a chain connection. The fertilizer wheel engagement groove 70208 on the fertilizer box contact head 70207 can be docked on the fertilizer transfer wheel 802. The connecting chain between the fertilizer box output gear 70202 and the fertilizer box input gear 70404 is also provided with a chain tensioning mechanism 710, the structure and connection method of which are the same as those of the seed box chain tensioning mechanism 705.

[0037] Pressing roller mechanism: The pressing roller bracket 602 is installed on the rear side of the sowing unit mechanism bracket 501 through the bolt shaft 601, and a fixed bracket 607 is provided at the bottom of the sowing unit mechanism bracket 501. One end of the pressing roller mechanism spring 605 is hung on the fixed bracket 607, and the other end is hung on the middle part of the pressing roller mechanism adjusting rod 604. The lower end shaft of the pressing roller mechanism adjusting rod 604 is connected to the pressing roller connecting rod 606, and the pressing roller connecting rod 606 is fixed on the pressing roller bracket 602. An adjusting rod position groove 608 is provided on the pressing roller bracket 602, and the upper section of the pressing roller mechanism adjusting rod 604 is placed in the adjusting rod position groove 608.

[0038] Pressing roller mechanism Fig. 20 , Fig.21 and Fig. 22 , the pressing roller mechanism is installed behind the seeding unit mechanism 5 (see Fig.28 , the connection relationship among the pressing roller mechanism, the seeding unit mechanism 5 and the bracket mechanism 7). The pressing roller bracket 602 is both the support frame of the whole mechanism and used to connect to the seeding unit mechanism 5 (the rear end of the upper seeding unit bracket 501 on the seeding unit mechanism 5). The pressing roller bracket 602 can rotate around the bolt shaft 601 with respect to the seeding unit bracket 501. The settings of the pressing roller mechanism adjusting rod 604, the pressing roller mechanism spring 605 and the fixed hanger 607 are to adjust the gravity of the pressing roller pressing the ground. See Fig.21 , the adjusting rod position slot 608 is opened on the upper surface of the pressing roller bracket 602 and is composed of a longitudinal slot and multiple transverse slots. The longitudinal slot and the transverse slots look like the character "丰" (abundant). In the longitudinal slot, the pressing roller mechanism adjusting rod 604 can move back and forth to increase the elastic force of the pressing roller mechanism spring 605. Through this elastic force, the pressing gravity exerted by the whole pressing roller mechanism on the pressing roller 603 is increased. The transverse slots are used to lock the pressing roller mechanism adjusting rod 604 in the adjusted position to prevent it from rebounding due to the elastic force of the pressing roller mechanism spring 605. The bottom of the pressing roller mechanism adjusting rod 604 is a ring that is sleeved on the pressing roller connecting rod 606 and can rotate freely. In this way, a relative adjustment fulcrum will be formed at the bottom of the pressing roller mechanism adjusting rod 604. In this way, when the pressing roller mechanism adjusting rod 604 is pulled back and forth, the spring will be stretched and contracted simultaneously. Through this structure, it can be seen that the pressing roller mechanism can rotate relative to the seeding unit mechanism 5, but the applied pressing force is completed by relying on two forces. The first is the gravity generated by the weight of this application, and the second is the gravity applied through the elastic force of the spring.

[0039] Seed box mechanism 9: See Fig.17 and Fig.18 , there is a seed box hook 902 at the front of the lower end of the seed box 901 that matches the bracket mechanism bracket 701. The rear side of the lower end of the seed box 901 is installed on the bracket mechanism bracket 701 through the seed box mounting frame 904. The seeding wheel 905 at the seed discharging mechanism 903 at the lower end of the seed box mechanism 9 is correspondingly clamped with the seed box contact head 70401; this part is not particularly critical and is to add some installation stability mechanisms to cooperate with the structure of the bracket mechanism bracket 701 of the present invention. The seed box hook 902 and the seed box mounting frame 904 are both mounting frames designed for the corresponding positions on the bracket mechanism bracket 701.

[0040] Fertilizer box mechanism 8: See Fig.19 , the fertilizer box 801 is installed on the bracket mechanism bracket 701 through the fertilizer box mounting bracket 803 at the bottom end, and the fertilizer box contact head 70207 is butted against the fertilizer distributing wheel 802; the setting of the fertilizer box mounting bracket 803 is also to facilitate the installation of the fertilizer box on the bracket mechanism bracket 701.

[0041] Seeding unit 5: see Figure 28-Figure 31 The upper end of the sowing monomer mechanism total bracket 503 is installed on the bracket mechanism bracket 701 through the sowing monomer mechanism upper bracket 703, the front end of the sowing monomer mechanism total bracket 503 is installed at the bottom of the front end of the bracket mechanism bracket 701, and the sowing monomer mechanism bracket 501 is installed at the rear bottom end of the sowing monomer mechanism total bracket 503; the disc knife mechanism, bionic wheel mechanism and auxiliary mechanism are installed below the sowing monomer mechanism total bracket 503.

[0042] Disc knife mechanism: Below the front end of the main bracket 503 of the sowing unit mechanism is an inwardly inclined oblique bracket 520, a disc knife hole 506 is opened in the middle of the oblique bracket 520, and the disc knife shaft 517 of the disc knife 515 is installed on the disc knife bearing frame on the side of the oblique bracket 520 through the disc knife bearing 516. The disc knife bearing frame is a bearing seat on the side of the oblique bracket 520 for the convenience of installing the bearing, which is fixed to the outer bush of the bearing, so that the disc knife can rotate.

[0043] Bionic wheel mechanism: The axis of the bionic wheel 4 is installed on the lower end of the wheel frame 509 through a bearing, and the bionic wheel 4 is placed on the outer sides of the two ends of the disc knife 515; the wheel frame mounting seat 519 is on the rear side of the lower end of the sowing unit mechanism general bracket 503, and a wheel frame mounting hole 512 is opened on the wheel frame mounting seat 519, and the upper end of the wheel frame 509 is installed on the wheel frame mounting hole 512 through a bolt shaft 514.

[0044] Auxiliary mechanism: that is, the wheel frame 509 positioning mechanism, a gear slot 513 is opened on the sowing unit mechanism main bracket 503, the gear rod 502 passes through the bottom of the gear slot 513 and is installed on the side wall of the sowing unit mechanism main bracket 503 through the gear rod shaft 510, and a positioning block 511 is provided on the bottom of the gear rod 502 corresponding to the wheel frame 509.

[0045] A scraper 508 is installed under the main bracket 503 of the sowing unit mechanism through the bracket; the seeding pipe 505 is against the side of the disc knife 515, and the seeding port under the seeding mechanism 903 is connected with the seeding pipe 505 through a seeding hose.

[0046] The sowing unit mechanism total support 503 is the support frame of the entire mechanism. It is installed on the bracket mechanism support 701 through two parts. The upper end is fixedly installed on the bracket mechanism support 701 through the sowing unit mechanism upper frame 703, and the front end is directly installed at the bottom of the front end of the bracket mechanism support 701 (see Fig.28 In order to clearly see the connection relationship between the various components, the pressing roller 603, the bionic wheel 4 and the seed disc 515 are removed in this figure). The oblique bracket 520 is integrated with the sowing monomer mechanism main bracket 503, and is located in front of the sowing monomer mechanism main bracket 503. In order to facilitate the installation of the disc knife, its top end is just installed at the bottom of the front end of the bracket mechanism bracket 701.

[0047] On the total support 503 of the seeding monomer mechanism, it is necessary to install the bionic wheel 4 (generally two are needed, and the two wheels are coaxially installed) and its mechanism, the disc cutter 515 and its mechanism, and some auxiliary mechanisms.

[0048] The bionic wheel 4 and its mechanism have two parts. One part is the part for mounting the bionic wheel, and the other part is the part for restricting the bionic wheel. See Fig.28 , The bionic wheel 4 is installed at the bottom of the wheel frame 509 through a shaft, a shaft seat, and a bearing (a shaft hole 507 is opened at the bottom of the wheel frame 509, and the wheel shaft of the bionic wheel 4 is inserted into this hole, and the wheel shaft of the bionic wheel 4 is then connected to this hole through a bearing). The bionic wheel 4 can roll at the bottom of the wheel frame 509, and the bionic wheel 4 contacts the ground.

[0049] The upper end of the wheel frame 509 is installed on the wheel frame mounting seat 519 in the form of a shaft, and the upper end of the wheel frame 509 can rotate around this shaft. Since the bionic wheel 4 is installed at the lower end of the wheel frame 509, relying on the self-weight of the bionic wheel 4 to naturally droop and contact the ground. When the ground is uneven, it may cause the bionic wheel 4 and the wheel frame 509 to bounce upward and fail to achieve the effect. Therefore, an upper limit mechanism (auxiliary mechanism: i.e., the wheel frame 509 positioning mechanism) is provided on the wheel frame 509. See Fig.29 , Looking from above, the gear slot 513 is similar to the character "丰" ( Fig.30 ), with multiple horizontal groove positioning slots and a vertical groove shifting slot. The shift lever 502 can be moved back and forth by hand in the vertical groove shifting slot, thereby changing the distance between the bottom end of the positioning pressure block 511 and the upper surface of the wheel frame 509, thus limiting the upward movement of the wheel frame 509 and trying to keep the bionic wheel 4 in contact with the ground.

[0050] The auxiliary mechanism part also includes a soil scraping knife, a seed discharging pipe, etc. The soil scraping knife is attached to the side of the disc cutter 515 in a sheet shape for scraping the soil adhered to its surface. The upper end of the seed discharging pipe is installed on the total support 503 of the seeding monomer mechanism, and it generally follows the shape of the inner side of the inclined support 520, and at the same time is close to the side of the disc cutter. The seed discharging port below the seeding mechanism 903 is inserted into the seed discharging pipe 505 from above through a seed discharging hose. In this way, the seeds coming from the seed box enter the seed discharging pipe 505 and are applied to the ground from the bottom end. There is a mud scraping plate 504 at the outer edge corresponding to the bionic wheel 4, and the upper end of the mud scraping plate 504 is installed on the total support 503 of the seeding monomer mechanism.

[0051] See Fig.30 , A fertilizer application port 518 is opened on the total support 503 of the seeding monomer mechanism, and the fertilizer discharging pipe 804 of the fertilizer box is inserted into the fertilizer application port 518; fertilizer is applied through this port.

[0052] Grass-splitting wheel mechanism 3: The grass-splitting wheel mechanism 3 is installed at the front end of the sowing unit mechanism main bracket 503 through the grass-splitting wheel mechanism seat 301, and a grass-splitting wheel frame 302 is installed on the grass-splitting wheel mechanism seat 301 through the grass-splitting wheel frame bolt shaft 311. The front end of the grass-splitting wheel frame 302 is bent inward, and a grass-splitting wheel 303 is installed at the bending part through the wheel shaft; the bottom end of the corrugated knife frame 305 is installed on the grass-splitting wheel mechanism seat 301, and the middle part is fixed to the grass-splitting wheel frame 302 through bolts; the corrugated knife shaft 308 is installed on the upper end of the corrugated knife frame 305, and two A set of knife shaft tapered bearings 307 is installed with a corrugated knife shaft sleeve 313, an oil chamber 310 is left between the two sets of knife shaft tapered bearings 307, an oil injection channel 309 is opened in the corrugated knife shaft 308, one end of the oil injection channel 309 is connected with the oil chamber 310, and the other end is connected to the outside from the side of the corrugated knife shaft 308, and an oil injection nozzle 312 is installed. The oil injection nozzle 312 is connected with the oil injection system through a connecting pipe, and a sealing cap 306 is installed at the outer end of the corrugated knife shaft 308. The edge of the sealing cap 306 and the corrugated knife 304 are fastened to the corrugated knife holder 305 by bolts.

[0053] See Figure 1 The grass-splitting wheel mechanism 3 is installed in front of the sowing unit mechanism 5. The grass-splitting wheel mechanism 3 and the sowing unit mechanism 5 are installed by connecting the grass-splitting wheel mechanism seat 301 and the sowing unit mechanism main bracket 503. Fig.33 It can be seen that two grass-splitting wheels 303 and one corrugated knife 304 need to be installed on the grass-splitting wheel mechanism 3. In order to achieve the grass-splitting effect, the two grass-splitting wheels 303 are positioned in an inward-facing eight-shaped form (which can be understood as the front end of the grass-splitting wheel frame 302 is bent inward), and the corrugated knife 304 is positioned between the two grass-splitting wheels 303. The two grass-splitting wheels 303 are respectively mounted on the front ends of the grass-splitting wheel frames 302 on both sides. The grass-splitting wheel frames 302 on both sides are fixedly connected by the bottom wheel frame crossbeams, and are fixed to the grass-splitting wheel mechanism seat 301 through the wheel frame crossbeam grass-splitting wheel frame bolt shaft 311.

[0054] Since the corrugated knife 304 is approximately located at the center between the grass-splitting wheel frames 302 on both sides, the bracket (corrugated knife seat 305) on which it is suspended belongs to the side bracket (see Fig.33 ), the corrugated knife seat 305 is fixed to the grass dividing wheel mechanism seat 301 and the grass dividing wheel frame 302 on one side by two sets of bolts. The corrugated knife shaft 308 is installed on the corrugated knife seat 305, and the corrugated knife 304 is installed on the corrugated knife shaft 308 through the corrugated knife shaft sleeve 313 and the knife shaft tapered bearing 307 (two sets).

[0055] Since the corrugated knife 304 is a corrugated knife shaft sleeve 313, a knife shaft tapered bearing 307 (two groups) installed on the corrugated knife shaft 308, and between the grass-splitting wheel frames 302 on both sides, in order to keep the bearing lubricated and rolling, and to prevent foreign matter from entering the bearing working cavity (that is, the cavity formed between the corrugated knife shaft sleeve 313 and the corrugated knife shaft 308, that is, the oil cavity 310), a lubricating oil sealing cavity (including the oil cavity 310) is provided, see Fig.34 This closed cavity is formed by an oil seal cover (sealing cap 306), a corrugated blade shaft sleeve 313 and a bearing end baffle 314. This cavity encloses the bearing (blade shaft tapered bearing 307). In order to inject lubricating oil into the cavity, an oil injection channel 309 is opened. The oil injection channel 309 is opened in the corrugated blade shaft 308, one end of which is connected to the outside world, and an oil injection nozzle 312 is added, and the other end is connected to the oil cavity 310. In this way, lubricating oil is added to the lubricating oil closed cavity through the oil injection nozzle 312.

The lower end of the telescopic inner rod 113 is inserted into the telescopic outer rod 114. A limiting groove 118 is provided on the telescopic outer rod 114. The limiting pin 117 on the telescopic inner rod 113 is placed in the limiting groove 118. A spring lower clamping plate 119 is arranged on the telescopic outer rod 114. The telescopic inner rod between the spring upper clamping plate 116 and the spring lower clamping plate 119 is The outer sleeve of the telescopic outer rod 113 and the telescopic outer rod 114 is provided with a return spring 104, the bottom end of the telescopic outer rod 114 is sleeved on the outer rod bolt shaft 120, the outer rod bolt shaft 120 is installed on the longitudinal connecting plate 108, and the longitudinal connecting plate 108 and the transverse connecting plate 110 are installed on the mounting shaft of the fertilizer cutter disc 106 through the bolt shaft, that is, the longitudinal connecting plate 108 and the transverse connecting plate 110 are coaxial with the fertilizer cutter disc 106, and the longitudinal connecting plate 108 and the transverse connecting plate 110 can be connected with the fertilizer cutter disc 106. The axis rotates about the axis, the other end of the horizontal connecting plate 110 is sleeved on the horizontal plate bolt axis 121, the horizontal plate bolt axis 121 is installed on the horizontal plate sleeve 111, and the horizontal plate sleeve 111 is installed at the bottom end of the fertilizer applicator adjustment frame 103; a soil cleaning knife 107 is installed at the front end of the longitudinal connecting plate 108 through a bracket, and the soil cleaning knife 107 is close to the surface of the fertilizer disc 106; the fertilizer guide tube 105 is installed on the sleeve of the fertilizer disc 106; a scraper knife 109 is installed on the inner side of the horizontal connecting plate 110.

[0057] See Figure 2 and Figure 3 The fertilizer spreader mechanism 1 is mounted on a fertilizer spreader mechanism mounting frame 1303 of the front frame 13. There are two sets, which are respectively mounted on both sides of the angle beam 1302 of the front frame 13. The two fertilizer spreader mechanisms 1 have the same structure, but the positions of the components are corresponding.

[0058] The fertilizer applicator mechanism 1 is fastened to the fertilizer applicator mechanism mounting frame 1303 by the cooperation of the fastening collar 101 and the bolt. The fastening collar 101 is sleeved on the fertilizer applicator mechanism mounting frame 1303. The end of the fastening collar 101 is inserted into the fertilizer applicator fixing frame 102, and the end is threaded. After being fastened with a nut, the fastening collar 101 tightly clamps the fertilizer applicator mechanism mounting frame 1303 between the fastening collar 101 and the fertilizer applicator fixing frame 102.

[0059] The fertilizer applicator adjusting frame 103 is plugged into the fertilizer applicator fixing frame 102. When it is not fastened by bolts, the height can be adjusted as needed. When it is adjusted to the required height, it can be fastened by bolts.

[0060] Two connecting frame sleeves (spring sleeve 112 and transverse plate sleeve 111) are installed in sequence from bottom to top on the fertilizer applicator adjustment frame 103, which are respectively used to install one end of the connecting spring assembly (reset spring 104 and its connecting assembly) and the connecting plate assembly (transverse connecting plate 110). Both of them are connected by bolts (bolts inserted in the spring sleeve 112 and transverse plate bolt shaft 121 inserted in the transverse plate sleeve 111), and can rotate around this axis.

[0061] See Fig.35 The other end of the transverse connecting plate 110 is installed at one end of the disk shaft of the fertilizer knife disc 106 together with the longitudinal connecting plate 108, and the transverse connecting plate 110 and the longitudinal connecting plate 108 can independently rotate around the disk shaft. In this way, the reset spring 104 and its connecting components, the transverse connecting plate 110, the longitudinal connecting plate 108 and the fertilizer applicator adjustment frame 103 form a mechanism similar to a four-bar linkage, and the four corners are connected in the form of axes and can rotate.

[0062] Return spring 104 and its connecting components: see Fig.38 This component is composed of two telescopic inner rods 113 and telescopic outer rods 114 that are plugged into each other. That is to say, the telescopic inner rod 113 is inserted into the telescopic outer rod 114, and the telescopic amount between them is limited by the cooperation of the limit pin 117 and the limit groove 118. The limit pin 117 is fixed on the telescopic inner rod 113, and the limit groove 118 is opened on the telescopic outer rod 114. The limit pin 117 can only slide in the limit groove 118.

[0064] Since the fertilizer applicator mechanism 1 is at the front end of the entire mechanism, the fertilizer disc 106 often contacts too much dry soil or wet soil, so a scraper 109 is installed on the transverse connecting plate 110. The scraper 109 is as close to the fertilizer disc 106 as possible, but does not move synchronously with the fertilizer disc 106 to scrape off the clay stuck on the fertilizer disc 106. At the same time, a cleaning knife 107 is installed at the front end of the longitudinal connecting plate 108 through a connecting frame. The cleaning knife 107 corresponds to the side of the blade of the scraper 109 to clean the soil at the blade of the fertilizer disc 106 and keep the fertilizer disc 106 clean as much as possible.

[0065] See Fig.35 On the shaft sleeve of the fertilizing knife disc 106, the position is roughly between the fertilizing knife disc 106 and the longitudinal connecting plate 108. The fertilizing pipe 1203 is a connecting hose, and its lower end is plugged into the upper end of the fertilizer outlet channel 105, so that the fertilizer in the large fertilizer box is applied to the ground from the bottom of the fertilizer outlet channel 105.
